In the video below, the man can be seen on the truck’s ladder and walking from end to end of the vehicle.

Police also were on the scene, and the man was administered an electric shock after coming down from the vehicle. He was taken to a hospital, which Prince George’s County Fire/EMS spokesman Mark Brady tells WTOP is standard procedure after a shock incident.

“It appeared he was on some type of substance which would also require evaluation at a hospital,” Brady says.
